Part of the issue with SLC-41 is that cadence is very low so you have equipment sitting around for long periods not doing much.

Now if they had a higher launch cadence then then equipment get used and tested more frequently.

Re: What was the fault?

Ground equipment at SLC-41 is a mixture of ULA and Space Force.

The following items have been performed on Hubble service missions, Clearly gyroscope replacement is feasible but nobody is saying it would be easy for a robot to do and lot of development still required,

The service mission meant astronauts hanging off the Canada arm and was incrediably difficult. There is a review of the last mission here. there is a point where they had to remove over 100 screws to get access. as luck whould have it they stripped the head of one of the screws holding on a hand rail. Solution with rip off the hand rail.

BTW, Space Force have cooled off on the idea of on orbit space servicing and refueling. I am guessing with improved payload capacity, reduced lanch cost and increased frequency its easier to replace than repair. just like consumer electronics, lol Why try a difficult refuelling mission when you easily launch with extra propellant in the first place.

Those solar-electric ion thrusters were made in the UK by Qinetiq. However the problem doesn't appear to be with the thrusters, rather the power supply to them.

Texan construction workers put a rocket up Team SpaceX over 'unpaid bills'

Oneman2Many

Depends on your products and market. For automotive there aren't many customers and so manufactures know its a limited market that isn't so easy to turn customers away. I've seen small suppliers go bust and to be honest most enterprises have an approved list of suppliers that they will have done due diligence on including financial stability. its why many of these smaller suppliers are supplying through a 3rd party which makes recovering money even harder.

As for reputation, everyone in the industry knows what the score is, its all about cash flow.

Oneman2Many

Pretty much all large companies are like this, squeeze suppliers till they go bust. Contract terms can be anything up to 180 days and they know the smaller supplier won't come after them as they are too afraid to lose business so they pay them last minute. At more than one company HQ I've seen bailiffs turn up over unpaid bills.

Hubble Space Telescope hasn't had any visitors for 15 years

Oneman2Many

This video shows how hard it is to service Hubble. Its widely been published that Jared Isaacman is proposing using one of the Polaris mission to service hubble using Dragon capsule. Polaris 2 due to launch next month has a very basic EVA planned so at least they will have a better idea of what is going to be possible. Their planned EVA is 2 hours which is a fraction of what will be needed for a hubble mission. The suit only has mobility in arms, not waist or legs so there is likely more development needed there. Who knows but as Jared says, if nothing else gets approved then what have they got to lose ?

Re: Not just the ailing components

They aren't taking about using a Falcon to do a retrieve mission. There is a rocket under development with a planned higher return payload capacity then shuttle had both for mass and volume.

The HST solar panels aren't designed to be folded away but I'm sure they can come up with a solutiom.

Clock is ticking for NASA to fix bucket of issues before next Artemis mission

While there are some valid points, the video does point out it doesn't have access to a lot of information. I expect there are parts where they aee further along that published and parts they are behind.

Re: After Tesla, SpaceX

Not sure who is signing off Polaris Dawn. The launch vehicle (F9) is human rate and dragon capsule is as well but they are making quite a big change and don't know about the suits that will be used for EVA which apparently a development of the existing suits they wear for launch & return. For NASA missions they would have certified them.

Oneman2Many

Re: After Tesla, SpaceX

That is why you have multiple options, Dragon, Starliner and Dreamchaser has a private contract.

And whiles the systems are privately developed they all have NASA oversight.

You know that Shuttle was privately developed and manufactured but operated by NASA. Stuttle was rockwell, RS-25 areojet rocketdyne, srb was Thiokol, etc

Oh and NASA has been working on their own human rated system, how is that working out for them.

Re: So, smart meter joy is continuing

Yes i know what a genny is and how it works but it should be on a clearly labelled isolator that can disconnect from grid feed.

Next you will be commenting on bi-directional ev chargers.

Oneman2Many

Re: So, smart meter joy is continuing

It not unusual to have 2 invertors, I have 2 myself due to having an older system on the original FIT and expanded it with a second hybrid invertor, more higher density panels, battery and EV charger. The installer had no issues swapping the meter. Everything is on isolation switches and clearly labelled, not hard to do.

Re: Mesh

Meters are already mesh capable. And why would spend billions on new infrastructure when one already exists ? If 2g was good enough for emergency services, its fine for smart meters

4g isn't going anywhere, Vodafone picked up a 15 year contract to connect smart meters last year.

https://www.ispreview.co.uk/index.php/2023/08/vodafone-uk-to-upgrade-energy-smart-meters-with-4g-mobile.html

And finally they don't need the bandwidth of 4g, its what is available.

Re: So, smart meter joy is continuing

To be honest, wouldn't consider it much different than having a battery in addition to an Inverter.

Octopus home mini links your smart meter to your internet connection for reporting. However it won't work for all customers with poor signal to the meter or those with no internet and yes there are those with no internet.

You would think they can read the dual feed warning stickers put on the grid supply by PV installers.

FAA gives SpaceX a bunch of homework to do before Starship flies again

Oneman2Many

My issues is that effectly SpaceX are self-certifying the clearance. I don't have any knowledge of what the behind the scenes discussions are but SpaceX and FAA have said many times that they are continously in contact so I doubt the publish report is the first itteration of it. How many times did FAA push back and get SpaceX to make changes ?

Oneman2Many

FAA didn't come up with. That is what SpaceX told the FAA what they plan to do There will be more details that SpaceX will have given to FAA.

Oneman2Many

As per last time, FAA didn't write the report or really have any input. The report is spacex reporting on issues they found and will correct and I suspect most of have already been implemented as there are things like design changes which would take months to implement (or years if you are Boeing). All the FAA are doing is agreeing with SpaceX findings. I can understand why is works this way as SpaceX are the SME on Starship so will know the most about what happened and how to prevent it in future but it does seem to make FAA rather toothless.

Re: Hmm ...

VeraCrypt doesn't support Active Directory, AFIAK it doesn't offer any support for central key storage or passwords. Probably a major requirement for most enterprises.

I suspect as well that you can access TPM even with it integrated but you are looking at some pretty specialist tools. Looks at what they managed to do with the locked iPhone from the US terrorist.

Re: A brilliant testament to analysis

This isn't a logon PIN, this is a bitlocker PIN which is different and I suspect no organisations have it switch on.

Oneman2Many

Re: A brilliant testament to analysis

You don't need GPO setting to show the option but yes the user will need to be a local admin which they aren't on most enterprise workstations.

Oneman2Many

It does need access to the LPC connector, the laptop used had the lanes exposed on a unused connector, other laptops may need chip to be de-soldered to gain access which to do be honest isn't going to stop a determined and semi-skilled bad actor.

It also needs a discrete TPM chip, which has been integrated with CPU since 6th gen on Intel back in 2015 (wonder why a 10 year old laptop was used ?).

Finally if you are worried then you can create a Bitlocker PIN which stops the attack however I suspect the majority of users don't do that.

Suffice to say that it goes to show that if somebody gains physical access to your device then it will be vulnerable.

Rocket Lab is a David among Goliaths in the space race

Re: Which rocket?

Not sure what your point is ?

Booster and Starship both exploded over the Gulf, not part of any national park. Stage 0 did rain debries down in national park but it wasn't the rocket.

I expect more from Peter Beck, he's had great interviews with Tim Dodd and NSF amongst other. He seems like a nice guy and obviously passionate about his company and rockets in general so I wasn't expected snidey remarks from him especially ones that are facturally incorrect.

Re: Prudent

Who says it won't be pushed out, HLS is only one of many issues that is holding the program up. SLS, Spacesuits, Orion capsule and I'm sure many others.

I assume you were joking about 'NASA had a chat with second place finisher' ? The major partner of that bid has left the consortium, I assume having lost the original competition there has been zero further development unlike SpaceX which would have carried on regardless of winning the contract on not. The contract awarded for 2nd lander is for 2028, it very unlikely they can pull ahead to any time sooner and I'm not even holding my breath about them making the 2028 schedule being a multi company partnership which historically has been a recipe for delays especially taking into account the members involved. So not sure where you get the idea that its some sort of race ?

I am not sure where you think Astrobotic recent lunar attempt comes into it. Its great the work they are doing but human flight is on a different scale to their plans. Assuming they leave the launch services to an established player (SLS, Starship, mayby New Glen) the lander part is billions of dollars to develop and with 2 human rated systems under development is there space for a 3rd player ?

As for Dreamchaser, I am guessing you are confused by its scope and where it would fit into Artimes program. Right now its being developed for cargo. They do have a contract (manybe ?) and potentially funding to provide crew transport services to LEO for Blue Reef so no trips to the moon. According to this site the first flight doesn't even had a date but won't be before 2029,

Re: Prudent

Where do you draw the line. SpaceX are talking about V2 and V3, does that mean they should wait even though V1 can still produce valid results ?

As for NASA, they have given up on 2025 or even 2026 for Artimes 3. I honestly won't be shocked if the delay landing to 2028 and Artimes 4.

As Broadcom nukes VMware's channel, the big winner is set to be Nutanix

Oneman2Many

KVM as the hypervisor is fine but you will need management tools and security hardening for on prem enterprise hosting.

Oneman2Many

I'm pretty sure that anybody who has been in the industry more than 5 minutes knew this was going to happen based on Broadcoms previous track record. Even before the aquisition, the change to core based licensing pushed costs up but as soon as there was whispers of Broadcom being in the running we knew the writing was on the wall for VMWare. As we have been banging on to our developers and vendors for the last 5 years, the future is CaaS and the hosting solution was never going to be Tanzu.

Its a shame, they have some solid products and there is nothing else that has management tools and 3rd party support that scale for enterprise hosting. Nutanix is OK for SMB but falls shorts when scaled up.

Re: Jared wants to help

Think the plan for the second mission is to test out EVA. Then work with NASA for a.repair on the next mission. Boosting orbit should be pretty easy. Replacing the gyroscopics will be difficult. There aren't any handholds and they don't have an arm to help them on EVA.

Hubble science instruments still out after going down 3 times in a week

Oneman2Many

Issacman is looking at this as part of Polaris missions. NASA had signed off on a feasibility study last year but not heard of any updates since.

First flight is due in first half of 2024 and they are planning a EVA so will see how feasible a service mission from a dragon capsule would be. Boosting the orbit shouldn't be an issue, NASA installed a mating ring on the last shuttle service to make that easier. The lack of a robotic arm apparently is a major issue for changing the gyros as there aren't any handgrips on Hubble.

BTW, this would be all be paid for Issacman and potentially SpaceX and any 3rd parties as companies such as Axiom who may be able to assist.
